Synergistic Mn‐MOF Activation of Pistol Ribozymes for Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A Mn2+‐based metal–organic framework delivers a catalytic Pistol ribozyme for targeted PD‐L1 mRNA cleavage in tumor cells, with the released Mn2+ not only inducing immune activation in immune cells but also increasing the Pistol ribozyme catalytic activity.

Engineered Small Extracellular Vesicles Targeting Tumor‐Associated Endothelial Cells to Effectively Remodel the Glioma Microenvironment

open access: yesAdvanced Science, EarlyView.
This study developed a novel drug delivery platform that overcomes the blood‐brain barrier in glioblastoma. By fusing IGFBP7 with small extracellular vesicles, the platform specifically targets tumor vasculature. It effectively delivers temozolomide, suppressing tumor growth at low doses.

TGFβ1 Activates Lnc‐APUE to Promote Tumor Metastasis via the Alu Element‐Driven STAU1‐Mediated Decay of CDH1 mRNA

open access: yesAdvanced Science, EarlyView.
We delineate a TGFβ1/SMAD/lnc‐APUE/E‐cadherin axis wherein TGFβ1 signaling activates lnc‐APUE; lnc‐APUE subsequently downregulates E‐cadherin expression via Alu element‐driven STAU1‐mediated decay of CDH1 mRNA, thereby promoting tumor metastasis. Our findings reveal a novel regulatory function for lnc‐APUE within the SMD pathway, elucidate a distinct ...

Targeted H2S Delivery System Attenuates Blood‐Spinal Cord Barrier Disruption after Spinal Cord Injury by Reshaping the Ferritinophagy Pathway

open access: yesAdvanced Science, EarlyView.
The αvβ3‐mediated SPRC@MPDA‐RGD targets broken endothelial cells and controllably releases SPRC. CSE is then activated to produce endogenous H2S, which inhibits ferritinophagy. In brief, H2S inhibits autophagy by activating the PI3K/Akt/mTOR pathway, thereby suppressing the ferroptosis process mediated by NCOA4, and ultimately promoting the ...

Ascites circRNA ASCOR Drives Platinum Resistance of High‐Grade Serous Ovarian Cancer by Facilitating RPA1 Nuclear Translocation

open access: yesAdvanced Science, EarlyView.
High‐grade serous ovarian carcinoma (HGSOC) is plagued by platinum resistance, with malignant ascites closely linked to poor outcomes. Here, we identify ASCOR, a circRNA enriched in ascites small extracellular vesicles (sEVs) from platinum‐resistant HGSOC patients, as a predictor of poor survival. ASCOR enhances platinum resistance in vitro and in vivo

Immunomodulatory Fibrous Scaffold with Dual Enzyme‐Mimic Activities Prevents Postsurgical Tumor Recurrence

open access: yesAdvanced Science, EarlyView.
A MnOx nanozyme‐functionalized electrospun fibrous scaffold is developed for postoperative therapy by leveraging its intrinsic physicochemical and immunomodulatory properties. Integrating POD‐ and CAT‐like activities, the scaffold induces immunogenic cell death, alleviates hypoxia, and reverses immunosuppression, while simultaneously recruiting and ...

Intrinsic PPG–ECG Coupling for Accurate and Low‐Power Blood Pressure Monitoring

open access: yesAdvanced Science, EarlyView.
A PPG–ECG coupling strategy for continuous blood pressure monitoring that intrinsically synchronizes signals within a single waveform is demonstrated, minimizing synchronization errors and hardware complexity. This approach halves power consumption while maintaining high accuracy, enabling compact, energy‐efficient wearable devices for personalized ...
